NETGEAR ReadyNAS OS 6 Rack-Mount Storage Systems

Safety Warnings

1. The equipment contains no operator access areas and is certified for installation only by
trained personnel, according to the installation instructions provided with each storage
system.
2. Install the socket outlet near the equipment in an easily accessible location.
3. Observe the on-board battery precautions. Follow the battery replacement instructions
explained in Replace the On-board Battery
DANGER:
Replacing the battery with an incorrect type creates a danger of
explosion. Replace the battery the same or an equivalent type
recommended by NETGEAR only. Dispose of used batteries
according to the manufacturer's instructions.
Installing the on-board battery upside down, which reverses its
polarities, creates a risk of explosion. Take care to install the
battery correctly.
4. Connect the storage systems and their associated LAN connections only to equipment
within the same building.
5. Slide or rail-mounted equipment is not to be used as a shelf or a work space.

Electrical Safety Precautions

Follow basic electrical safety precautions to protect yourself from harm and the ReadyNAS
from damage:
• Be aware of the locations of the Power on/off switch on the chassis as well as the room's
emergency power-off switch, disconnection switch, or electrical outlet. If an electrical
accident occurs, you can then quickly remove power from the system.
• Do not work alone when working with high-voltage components.
• Always disconnect power from the system when removing or installing main system
components, such as the main board or memory modules. When disconnecting power,
first power down the system with the operating system and then unplug the power cords
of all the power supply storage systems in the system.
• When working around exposed electrical circuits, ensure that another person who is
familiar with the power-off controls is nearby to switch off the power if necessary.
• Use only one hand when working with powered-on electrical equipment. This is to avoid
making a complete circuit, which will cause electrical shock. Use extreme caution when
on page 33.
